Improved precision navigation systems and methods are provided. In one embodiment, a navigation system is provided. The system comprises a global navigation satellite system receiver adapted to output information representing the location of a vehicle based on one or more signals from one or more satellites; an ultra-wideband ranging system adapted to output information representing the location of the vehicle based on one or more ultra-wideband signals; and a vehicle guidance system coupled to receive the location output from the global navigation satellite system receiver and the location output from the ultra-wideband ranging system. The vehicle guidance system is adapted to maneuver the vehicle based on the information from at least one of the global navigation satellite system receiver and the ultra-wideband ranging system based on a distance of the vehicle from a target object.
